To shoot Crunch Gym’s AirBarre class for our January issue, we called in the expert who helped launch it: Christopher Harrison. (You might recognize his name from last Fall, when he choreographed Alexander Wang’s show-stopping H&M runway performance.)

As the founder and co-creator of AntiGravity® Fitness, Harrison’s aerial approach to exercise has gained a following for its ability to help participants develop the elegant, strong muscles of a dancer—while floating three feet above the ground in a silk hammock. During the AirBarre classes, participants will use the silks to assist with ballet-inspired exercises and during stretches. Check out the video below to see how the gorgeous pose that ran in the magazine came together, and hit up Crunch or AntigravityFitness to get in on the high-flying fun yourself.
